enhance SchemaObject type for composition types

[uwinkelvos]

Composition types (allOf, anyOf, oneOf and not) are valid SchemaObjects according to the spec, but right now anything without type could not be assigned as a schema.

Hey @cdimascio! First of all thanks for all your work here! We use express-openapi-validator with .ts schema files and realized the typing of some schema objects is not correct. So this typing only change will solve this problem. Would be nice to get this into a next release! Thanks a lot!

Hey @cdimascio: Could you find the time to have a quick look at this change? It's just typing level with no runtime code change and would spare typescript users a lot of insecure and redundant type assertions.

Hey @cdimascio! I updated my branch, status checks pass. Is there anything else I can do?

[uwinkelvos]

Hey @cdimascio, any thoughts about this?

Hey @cdimascio: New year next try! ;)

Thanks a lot! This fixes quite some cases where we had to "unknown-assert" parts of the schema before! :)
